Got mail?  The U.S. Postal Service (USPS) has a postal station here on the SMC campus.

P.O. boxes are assigned to ALL undergraduate resident students of SMC.  If a student does not want their assigned P.O. Box, they should contact the Post Office directly to close the box and avoid charges.

Undergraduate residents will receive the P.O. Box number and the key within the first week of the fall semester.  The cost is $1.00, paid to the US Post Office. 

All letter mail and packages should be sent to the residents P.O. Box (except FedEx or UPS - see below Non-P.O. Box Mail)

This will be your mailing address while you live on campus:
Your Name
PO Box #______
Moraga, CA 94575

Non-P.O. Box Mail

In order to receive packages sent via FedEx or UPS, senders should address the package as follows:

Your Name
Saint Mary's College - Resident Student
1928 Saint Mary's Road
Moraga, CA 94556
Resident Phone Number

These packages are mailed to the Warehouse on campus.  The Warehouse will contact the resident via phone number to arrange pick-up.  The Warehouse can be reached at 925-631-4355, Monday - Friday 8:00 am - 4:00 pm.

End of the year procedures: 

  • Spring Move-Out / Fall Return: Resident undergraduate students moving out of the halls at the end of spring semester and returning in the fall, must submit a Re-mail Form directly to the Post Office before checking out of the residence halls in May. There is a $35 charge per month for re-mailing and the cost is due at the end of the Spring term. SMC Post Office will only "re-mail" first class mail and the rest will be returned to sender. Packages for returning students will be held until the beginning of the Fall semester.  Failure to do so may result in a fine and a loss of the current P.O. Box number resulting in a new address for the next semester.
  • Spring Move-Out / No Return:  Residents moving off campus in May who are not returning to live on campus in the fall need to close their P.O. Box and return the key to the SMC Post Office by May 31st. Failure to close or return the Post Office key may result in a an improper check out fee  and/or a re-keying fine. There is a $1.00 charge for lost or misplaced keys, and/or a $23.00 lock change fee if replacement keys are unavailable.
  • Summer Stays:  Residents living on campus during the summer should make arrangements with the Post Office to keep the same P.O. Box for the summer. Any summer resident student moving off campus at the end of the summer who is not going to live on campus in the Fall must return their PO Box key to the SMC Post Office before checking out at the end of the summer. Summer boxes can be rented for the summer (3 months) at $22.50.

The Post Office does not hold mail and will return all mail to sender and assess fines if the above procedures are not followed.

If all proper procedures are followed, students who return for fall should have the same P.O. Box they were assigned the semester before.  In addition it is a good idea for returning students to again submit forwarding forms in September so that mail will come to their College address rather than their summer address.

Checking Your Mail

It is important that you check your mail regularly, especially if you are subscribing to publications or daily / weekly periodicals.  Overflow of your mailbox may result in a $605 bi-annual holding charge.

If you receive mail that does not belong to you, the Post Office invites you to simply push it back through the box and the Post Office administrator will pick it up and place it in the correct box.

Notifications in Your P.O. Box

  • Box holders may find a small yellow postcard in their box notifying the holder that a received parcel needs to be picked up in the Post Office during business hours with a photo ID.  
  • A tagged key will be placed in a box if the holder receives a package too large to fit in the box.  The number on the tagged key is the number of the box in the Post Office holding that received package and should be picked up in a timely manner.

Any questions regarding the policies and procedures should be directed to the Post Office.
